黄瓜是雌雄同株异花作物,其产量的高低与雌花发生的早晚和数量有密切关系.特别是近几年来对杂种优势的研究证明,黄瓜杂种一代具有早熟、丰产、抗病等优点,利用价值很高,但由于其雌雄花几乎同时开放,制种时需控制杂交,手续麻烦,工效太低.因此,控制黄瓜的性别,不仅在理论上而且在实践上都有重大意义.为促进黄瓜雌花早现,并提高其比
Cucumber is a monoecious allogamy crop, and its yield is closely related to the occurrence and the quantity of female flowers.In particular, the studies on heterosis in recent years have proved that the cucumber hybrids have the advantages of early maturity, high yield, disease resistance, etc. The value is very high, but because of its male and female flowers are almost open at the same time, the need to control the hybridization of seed production, the procedure is cumbersome, the work efficiency is too low.Therefore, controlling the gender of cucumber is not only of great theoretical and practical significance.For the promotion of cucumber Female flowers appear early, and improve its ratio
